-It becomes larger in a person who carries large heavy trays overhead, as does a waitperson. -It is located on the humerus. -It is the site of attachment for the deltoid. -It is relatively larger in a male than in a female. -***There are no exceptions; all of the above are true***

Compared with the male pelvis, the female pelvis has

-an enlarged pelvic outlet. -a wider, more circular pelvic inlet. -a broader pubic arch. -***all of the above***

The only point of articulation between the pectoral girdle and the axial skeleton is at (the)

The appendicular skeleton

-includes the bones of the upper limbs -includes the bones of the lower limbs -includes the bones that connect the limbs to the axial skeleton -includes girdles -***all of the above are correct***

The pelvis

-is dramatically different in males and females. -is a composite structure. -contains bones from both the axial and the appendicular skeleton. -protects pelvic organs. -***is all of the above***

Differences between a child's skeleton and that of a small adult include which of the following?

In the child's skeleton a metopic suture is present.

What is the role of the fibula in articulations of the leg?

It articulates both proximally and distally with the tibia.

Which of the following is true of the bony matrix of the skeleton as people age?

Its mineral content diminishes as a normal part of aging.

Why is it difficult to distinguish the skeleton of a young male from that of a young female?

The characteristic greater density of bone that develops in adult males has not appeared in children. and Secondary sexual characteristics that cause skeletal differences between males and females do not appear prior to puberty.

Which event occurs first as an individual grows and ages?

The ossification centers of the occipital bone fuse.

Characteristics that specifically identify a skeletal element as belonging to a female include

a bone with smaller prominences and a smoother surface.

The socket that receives the head of the femur is the

acetabulum.

The structure of the os coxa that can easily be felt on the front of the hip is the

anterior superior iliac spine.

Which of the following bones are not in contact with the humerus?

carpals

The pectoral girdle consists of the

clavicle and scapula

The pectoral girdle meets the axial skeleton where the

clavicle attaches to the manubrium.

The clavicle

connects the pectoral girdle and axial skeleton

The depression on the distal end of the anterior humerus is (the)

coronoid fossa.

The distal end of the fibula

forms the lateral malleolus.

The largest nerve in the body passes through the

greater sciatic notch

The lateral contour of the shoulder is formed by what part of the humerus?

greater tubercle

The radial structures in contact with the ulna include the

head and ulnar notch

The trochlea is a part of the

humerus.

The bones of the pelvis

include both axial and appendicular elements

The origin of a portion of the triceps brachii is on the

infraglenoid tubercle.

What types of information about an individual's medical condition can the skeleton reveal?

injuries, such as broken bones and the presence of osteoarthritis

The patella

is a sesamoid bone

The pubic symphysis in females

is more subject to stretching under hormonal influence than that in males.

The surgical neck of the humerus corresponds to (the)

metaphysis of the bone.

The arches of the foot are partly supported by (the)

metatarsal bones.

Compared with the pectoral girdle, the pelvic girdle is

more robust, adapted for weight bearing

Which of the following is not a structure of the scapula?

olecranon

The pelvic girdle meets the axial skeleton where the

ossa coxae meet the sacrum.

Compared with that of females, the male coccyx

points more anteriorly.

The fibula

provides lateral stability to the ankle.

A muscle that flexes the forearm is attached to (the)

radial tuberosity

Most of the anterior surface of the scapula is formed by the

subscapular fossa.

The corners of the scapula include (the)

superior angle, inferior angle, and lateral angle.

In the ankle, the only tarsal bone that articulates with the leg bones is the

talus.

The boundaries of the false (or greater) pelvis include

the bladelike portions of each ilium.

Age of a skeleton can be determined from

the degree of ossification of cranial sutures and the number of teeth present.

The pelvic girdle consists of

the ilium, ischium, and pubis

Examination of what features of the skeleton can provide information about the health of an individual?

the number of carpal elements and appearance of healed fractures

Most bones in the appendicular skeleton develop from

the process of endochondral ossification and hyaline cartilage.

A wedding ring is traditionally worn around which bone?

the proximal phalanx of digit four of the manus

Fusion of the epiphyseal cartilages of long bones typically begins around the age of

three years.
